GAS-LAMP.

Specification of Letters Patent.

Patented May 26, 1914.

Application filed July 18, 1913. Serial No. 779,706.

To all whom it may concern Be it known that I, ALFRED I-I. HUMPHREY, a citizen of the United States, residing at New York, N. Y., have invented certain new and useful Improvements in Gas-Lamps, of

' which the following is a specification.

This invention relates to improvements in gas lamps.

My invention relates partlcularly to improvements in gas lamps of the indirect type or semi-indirect type, as they are sometimes called; that is, gas lamps in which the light is reflected upwardly from an opaque or semi-opaque or translucent globe closingthe lower part of the lamp.

The main objects of this invention are: First, to provide an improved gas lamp of the indirect type. Second, to provide an improved gas lamp of the indirect type where the bowl or globe is closed beneath and open at its top and the parts so arranged that the light rays reflected upwardly and outwardly from the inner surface of the bowl will be practically shadowless. Third, to provide an improved indirect gas lamp in which the operating parts are so arranged as to be entirely out of the path of the prodnets of combustion. Fourth, to provide an improved gas lamp of theindirect type in which the parts are so arranged that the products of combustion escape without unduly heating any portion of the lamp, and at the same time do not interfere with the air supply to .the burner, the air being effectively delivered to the mixing tube and to the burner at the point of combustion. Fifth, to provide an improved gas lamp of the indirect type, which is very easily cared for,-that is, the globe is accessible for cleaning and the mantle and burner parts are all fully accessible.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this'specification, in which:

Figure I is a perspective'view of my improved gas lamp. Fig. II is a detail top perinvention is clearly defined and spective view, with the globe' holder and globe removed. Fig. III 'is a similar detail perspective view, from the under side, with the globe holder open. Fig. IV is a detail vertical section through the pilot valve casing. Fig. V is a detail vertical section on a line corresponding to line of Fig.- IV.

'Fig. VI is an enlarged detail vertical section through the burner valve casing and parts of the burner. larged detail section through the hinge of the globe holder. Fig. VIII is a detail plan view of the upper part of the lamp. Fig. IX is a detail vertical section on a line corresponding to line 99 of Fig. VIII. Fig.

Fig. VII is an en-- X is a detail vertical section through the globe holder latch.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the lettered parts of the drawing, the supply pipe 1 is adapted as a support for the lamp. I provide a skeleton frame consisting in the structure illustrated of the coupling or top member 2 having arms 8 thereon. Depending from these arms 8 are side members or hangers 4, 5 and 6; the hangers 4 and 5 being adapted as gas delivery conduits; the hanger 6 being a dummy. The side members or hangers diverge downwardly and are uniformly spaced. At the upper ends ofcthe hangers is an ornamental member 7 which is held in place by the members 8 sleevedupon the side members or hangers and secured to support the member 7 by means of set screws 9.

The burner valve casing 10 and the pilot valve casing 11 are adapted as coupling members for connecting the hangers 4c and 5 respectively to the supporting ring 19. The pilot valve casing 11 is of the same shape-as the coupling member 13, the main valve casing being modified in shape only as is necessary to perform its functions.

The main burner valve 14 is of the rolary type. The valve actuating mechanism is an adaptation of that shown in my Reissue Patent, No. 13,552, dated April F 1912, and as it forms no part of my plGStrfl invention, I do not describe the same in detail herein.

In the valve casing 10, below the valve 1%, is a gas nozzle valve casing 15 communieating with the passage of the main light rays upwardly around the burner valve casing andhaving a nozzle 16 thereon. Theregulating valve 17 for the nozzle is disposed below the valve 1% as shown in. Fig. VI, and parallel therewith. The value casing 10 is u'ovided with a nipple 18 for the mixing tube 19. p

The burner 20 is of the inverted type and is provided with. a horizontally disposed in let passage member 21 adapted to receive the-horizontally disposed mixing tube 19. To assist in supporting the burner and to prevent its rotation on the mixing tube I provide a rod-like supporting arm 22, which. is carried by the perforated downwardly projecting ear on the under side or the valve casing 10, the burner passage member 21 being provided with a downwardly projecting ear 24 adapted to slidably engage this supporting arm. The burner is thus etfectively supported in a manner that permits its being freely removed occasion requires. The pilot 25 is mounted on the valve casing 11- and projects into a suitable proximity to the burner. The pilot flame 1s regulatedby means of the valve See Fi IV. The ring 12 is formed of a strip of iron, its ends being secured to the valve casing 10 on opposite sides of the nozzle valve casing by means of the-screws 2. See Fig. Ill. The 'lobe 28 is suitably sup-- ported in the glofie holder 29 which is mounted on the ring 12 by means of the hinge 30. This hinge is disposed opposite to the valve casing 10 so that the globe swing-s away from the parts of the lamp which require cleaning and adjustment. The globe swings ei'itirely clear so that the burners are lireelj accessible for adjustment or renewal of the mantles, or for other adjIHt-inent or regulation or cleaning of the luuner. The-globe hohler is held in its elooal position by the l'atch pin 31. See Fig. Til. Flll'i latch pin is held in engagement by means of the coiled spring supported in a suitable housing 33 on the inner side of the globe holder 29. This globe holder 29 is preferably made ornamental as it is substantially the only metal part exposed below the hanqers or side members of the frame.

The globe is open at the top and the lamp entirely open above the globe holder. The globe holder in the structure illustrated incloses the member 12 and also the pilot and the nozzle regulating: valves, the stem of th valve 14 projecting over the same. so that its actuating lever El l is outside of the globe holder as shown. The air inlets 35 of the mixing tube are adjacent to the periphery oi tho globe holder. but below the plane of the upper edge thcreol".

The lamp, being entirely open above the burner and there being no operating or metal parts to obs-strict the 'iassage o l the ll'll'Ollgll the skeleton :trame, is therefore rendered practically shadowless. Also, as all the operating parts of the lamp and metal room lions, the ornamental hanger menihers. the ormunental "lobe rin to ether If! 2'2 F) with the valves, burner tuber-1, and other opcrating parts are entirely outside of the path of the products of combustion, and therefore do not b come heated. enmigh to interlere with the successful operation of the lamp or enough to spoil the finish, and the prca'lucls of combustion do not contact there with sullicieutly to tarnish. Further, owing to the unobstructed centeabove the burner and the wide open globe or bowl, reflected light rays are con'lnnmicated from the inner surface of the bowl over a wide area and'the reflected heat rays are, to a large degree, distributed, as are the light rays. The lamp be ing fully open, the ascensional force or the products of combustion from the burner is so greatly reduced as not to affect the ornamen-. tal top.

The lamp being entirely open above the burner, causes a central upward current and draws fresh air to the burners to properly maintain combustion at that point and also to furnish a supply of fresh air to the ports 35 of the mixing tube. The burners thus supported are well protected from: draft" of air, the lamp, of course, being designml for inside lighting, and the parts are at the same time so constructed that none ol. them become unduly or excessively heated.

A further advantage is the ornamental lealure of the lamp. By usingan opaque or semi'opaque or translucent globe, the light reflected wnvardly, and, as stated, there are no parts to cast shadows, thus making a 105 l'iighly desirable cmistruction. My improved lamp is also desiral'ilc on account of the simplicity and economy of structure, and the efise'with which it may be cared for. v,

I have illustrated and described my improved lamp in detail in the form in which I have emlmdicd the same. I have notattempted to illustrate or describe certain modifications and details which I contemplate as I believe the disclosures made will enable those skilled in the art to which this invention relates to embodyor adapt the same as conditions may require.
